Vancouver, British Columbia–(Newsfile Corp. – November 25, 2025) – Sitka Gold Corp. (TSXV: SIG) (FSE: 1RF) (OTCQB: SITKF) (“Sitka” or the “Company”) is pleased to announce additional analytical results from drilling completed at its 100% owned, road accessible RC Gold Project (“RC Gold” or the “Project”) within the Yukon’s prolific Tombstone Gold Belt. Drilling at the Blackjack area has expanded the known mineralized envelope at the Blackjack Gold Deposit, expanded the Saddle Zone gold mineralization, identified a deeper zone of strong gold mineralization at Saddle, and discovered a new area of gold mineralization at Blackjack South located approximately 300 metres south of the current Blackjack deposit and within the current proposed pit limits.

At the Blackjack Deposit, drill hole DDRCCC-25-099 intersected 310.0 m of 0.61 g/t gold, including 172.4 m of 0.90 g/t gold and 26.8 m of 1.04 g/t gold, and 33.4 m of 2.40 g/t gold at the edge of the current MRE extending the known mineralization further to the southwest (see Figure 1). DDRCCC-25-102 returned 191.8 metres of 0.65 g/t gold including 24.3 m of 2.33 g/t gold, highlighting the presence of strong gold mineralization outside the southwest margin of the current MRE (see Figure 1).

At the Saddle Zone DDRCCC-25-104 intersected 44.4 metres of 1.33 g/t gold from 4.6 metres extending the near surface mineralization at the Saddle Zone further to the west (see Figure 1). The Saddle Zone is within the pit limits of the Blackjack Deposit but is not included in the current MRE and drilling has extended the strike of mineralization at Saddle to approximately 300 metres. Drilling at Blackjack South (holes DDRCCC-25-105, -108, -110) has intersected a new quartz monzonite dyke within the proposed pit limits at Blackjack, adding a new mineralized target approximately 300 metres south of the current MRE boundary where drillhole DDRCCC-25-110 intersected 44.5 m of 0.70 g/t gold including 8.8 metres of 1.18 g/t gold. Mineralization at Blackjack south consists of sheeted quartz veins cutting the feldspar megacrystic quartz monzonite and adjacent metasediments.

“Drilling at the Blackjack and Saddle zones continues to reinforce the potential for significant ounces to be added within the conceptual pit shell of our Blackjack gold deposit,” stated Cor Coe, CEO and Director of Sitka Gold. “While the long, robust drill intercepts returned this season continue to expand the mineralized envelope at Blackjack, which remains open in all directions, we are quite excited with what we are seeing at Saddle, where results such as 44.4 metres of 1.33 g/t gold beginning at surface in hole 104 highlight the potential to add near surface higher-grade gold mineralization within the proposed pit limits. Furthermore, results such as the 4.0 metres of 3.90 g/t gold beginning at 142.0 metres in hole 098 suggest that a deeper zone of higher-grade mineralization is also beginning to emerge at Saddle. In addition, a new zone of gold mineralization has been discovered about 300 metres south of the Blackjack resource envelope where step out drilling has intercepted strong gold values such as 44.5 metres of 0.70 g/t gold in hole 110, which included 8.8 metres of 1.18 g/t gold and a separate interval of 2.0 metres of 4.07 g/t gold. We look forward to following up on these latest drill results as we continue to unlock the potential at the Blackjack deposit, which is just one of our many exciting targets within what is quickly becoming a district-scale, multi-deposit gold camp at RC Gold.”

Blackjack Drilling

Drilling at Blackjack in 2025 which included 26 holes for approximately 10,494 m was successful in extending the known mineralization at the Blackjack deposit as well as extending the strike length of known mineralization at the Saddle zone, identifying new deeper mineralization at Saddle, and identifying new mineralization at Blackjack South. The three holes drilled at Blackjack South were successful at identifying a new zone of mineralization within the proposed Blackjack pit outline.

At the Saddle Zone, 11 holes for a total 2,918 meters have been completed in 2025. Received results continue to define the presence of dykes and sills with strong gold mineralization hosted both within the dykes and sills and the host metasedimentary rock. The near surface gold mineralization defined to date at the Saddle Zone is within the current proposed pit outline for the Blackjack Deposit resource, but is approximately 300 metres east of the current Mineral Resource Estimate (MRE) outline. This mineralization therefore has the potential to expand and add ounces to the current MRE. In addition, drill holes at Saddle have intersected a deeper zone of mineralization such as drillhole DDRCCC-25-086 which intersected a second deeper zone of 4.1 m of 1.45 g/t gold and DDRCCC-25-089 which intersected a second deeper zone of 4.0 m of 4.52 g/t gold from 236.0 m within mineralized dykes and sills (see news release dated September 4, 2025).

* While visible gold observations are very encouraging and confirm the presence of gold mineralization, they are not intended to imply potential gold grades. Gold assays will be published after they are received from the lab for mineralized intervals in which visible gold particles were noted.

Quality Assurance/Quality Control

On receipt from the drill site, the HTW/NTW-sized drill core was systematically logged for geological attributes, photographed and sampled at Sitka’s core logging facility. Sample lengths as small as 0.3 m were used to isolate features of interest, otherwise a default 2 m downhole sample length was used. Each sample is identified by a unique sample tag number which is placed in the bag containing the core to be assayed. Core was cut in half lengthwise along a predetermined line, with one-half (same half, consistently) collected for analysis and one-half stored as a record. Standard reference materials, blanks and duplicate samples were inserted by Sitka personnel at regular intervals into the sample stream. Bagged samples were placed in secure bins to ensure integrity during transport. They were delivered by Sitka personnel or a contract expeditor to ALS Laboratories’ preparatory facility in Whitehorse, Yukon, with analyses completed in North Vancouver.

ALS is accredited to ISO 17025:2005 UKAS ref. 4028 for its laboratory analysis. Samples were crushed by ALS to over 70 per cent passing below two millimetres and split using a riffle splitter. One-thousand-gram splits were pulverized to over 85 per cent passing below 75 microns. Gold determinations are by fire assay with an inductively coupled plasma mass spectroscopy (ICP-AES) finish on 50 g subsamples of the prepared pulp (ALS code: Au-ICP-22). Any sample returning over 10 g/t gold was re-analyzed by fire assay with a gravimetric finish on a 50 g subsample (ALS code: Au-GRA21). In addition, a 51-element analysis was performed on a 0.5 g subsample of the prepared pulps by an aqua regia digestion followed by an inductively coupled plasma mass spectroscopy (ICP-MS) finish (ALS code: ME-MS41).

About Sitka’s Flagship RC Gold Project

Sitka’s 100% owned RC Gold Project consists of a 431 square kilometre contiguous district-scale land package located in the heart of Yukon’s Tombstone Gold Belt. The project is located approximately 100 kilometres east of Dawson City, which has a 5,000 foot paved runway, and is accessed via a secondary gravel road from the Klondike Highway which is usable year-round and is an approximate 2 hour drive from Dawson City. It is the largest consolidated land package strategically positioned mid-way between the Eagle Gold Mine and the past producing Brewery Creek Gold Mine.

The RC Gold Project now has pit-constrained mineral resources that are contained in two zones: the Blackjack and Eiger gold deposits with 1,291,000 ounces of gold in 39,962,000 tonnes grading 1.01 g/t gold in an indicated category and 1,044,000 ounces of gold in 34,603,000 tonnes grading 0.94 g/t in an inferred category at Blackjack and 440,000 ounces of gold in 27,362,000 tonnes grading 0.50 g/t gold in an inferred category at Eiger. These resource estimate numbers are supported by the recently updated technical report for RC Gold, prepared in accordance with NI 43-101 standards, entitled “Clear Creek Property, RC Gold Project NI 43-101 Technical Report Dawson Mining District, Yukon Territory”, prepared by Ronald G. Simpson, P. Geo., of GeoSim Services Inc. with an effective date of January 21, 2025. This report is available on SEDAR+ (http://www.sedarplus.ca) and on the Company’s website (www.sitkagoldcorp.com).

Both of these deposits begin at surface, are potentially open pit minable and Initial bottle roll metallurgical testing confirmed the non-refractory characteristics of the gold mineralization and returned gold extraction rates averaging around 85%. Further metallurgical testwork in 2024 returned recoveries ranging from 77.6 to 93% for gravity followed by cyanidation.

For the purposes of the current resource model, it is assumed that a likely mill flowsheet would consist of a gravimetric, flotation, and cyanidation circuit.

The company has now completed 165 diamond drill holes for a total of 59,770 metres across the Clear Creek Intrusive Complex (CCIC), and an additional 3 holes for 858 metres in the May-Qu Intrusion. Drilling continues to outline higher grade mineralization at all zones including hole DDRCCC-24-068 at Blackjack which intersected 678.1 metres of 1.04 g/t gold starting from surface (see news release dated October 21, 2024), and hole DDRCCC-25-075 which intersected 352.8 metres of 1.55 g/t gold including 108.9 metres of 3.27 g/t gold and 45.0 metres of 4.52 g/t gold (see news release dated April 22, 2025). Drilling in 2024/2025 has resulted in the discovery of a new higher grade zone at Rhosggobel including hole DDRCRG-25-010 at Rhosgobel which intersected 235.9 metres of 1.11 g/t gold, including 40.0 m of 2.01 g/t gold and 10.0 m of 5.29 g/t gold, from surface (see news release dated September 18, 2025).
